Electricity station in TikZ

This is really just to inform you about the perspective library. Your target picture seems to be drawn in perspective, so you may want to check it out. A possible starting point for the power station is

\documentclass[tikz,border=3mm]{standalone}
\usetikzlibrary{perspective}

This is certainly just a start, but arguably using 3d coordinates makes it easier to draw these things, and you can change the view later if needed.

One may make things simpler by introducing styles for the planes, and more realistic by computing the visibility angles.

You can then vary the view parameters.
